Radiofrequency ablation of the pulmonary veins has been used to treat patients with paroxysmal atrial fibrillation (AF), and atrial damage after ablation is an issue of concern. To evaluate left… (More)

OBJECTIVES
To evaluate if radiofrequency catheter ablation is an effective procedure for the treatment of right ventricular outflow tract premature ventricular contractions (RVOT-PVC) and ascertain… (More)

OBJECTIVES
Both ablation catheters with closed irrigated system and 8mm tip-catheters have been shown to be more effective for typical atrial flutter radiofrequency (RF) ablation when compared to… (More)

OBJECTIVES
The aim of this study was to prospectively evaluate the sensitivity, specificity, and positive and negative predictive values of previously described ECG criteria to identify preexcited… (More)

OBJECTIVE
To determine the effectiveness of surgical isolation of the left atrial posterior wall encompassing the ostia of the pulmonary veins for the treatment of atrial fibrillation of rheumatic… (More)

OBJECTIVE

BACKGROUND
Radiofrequency ablation (RFA) in children is an increasingly common practice.
OBJECTIVE
To evaluate, in our institution, the results of RFA in children younger than 15 years.
METHODS
A… (More)

OBJECTIVE
